A client with chronic obstructive pulmonary disease (COPD) is experiencing shortness of breath and has a prescription for oxygen therapy. What is the maximum amount of oxygen the nurse should administer without a healthcare provider's order?
- A. 2 liters per minute
- B. 4 liters per minute
- C. 6 liters per minute
- D. 8 liters per minute
Correct Answer: B
Rationale: The correct answer is 4 liters per minute. Without a healthcare provider's order, the nurse should administer a maximum of 4 liters per minute of oxygen to prevent carbon dioxide retention in COPD clients. Higher flow rates can lead to oxygen toxicity and worsen the client's condition. Choices A, C, and D exceed the safe limit for oxygen administration without a healthcare provider's order.

In caring for a client who is receiving linezolid IV for nosocomial pneumonia, which assessment finding is most important for the nurse to report to the healthcare provider?
- A. Watery diarrhea
- B. Nausea
- C. Headache
- D. Dizziness
Correct Answer: A
Rationale: The correct answer is A: Watery diarrhea. This finding is the most important to report as it may indicate Clostridioides difficile infection, a severe side effect of antibiotic therapy. Clostridioides difficile infection can lead to serious complications and requires immediate medical attention. Choices B, C, and D are common side effects of linezolid but are not as critical as watery diarrhea in this context.
A client with cirrhosis is admitted with jaundice and ascites. Which assessment finding requires immediate intervention?
- A. Peripheral edema
- B. Confusion and altered mental status
- C. Yellowing of the skin
- D. Increased abdominal girth
Correct Answer: B
Rationale: Confusion and altered mental status are the most critical assessment findings in a client with cirrhosis. These symptoms may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Yellowing of the skin (jaundice) is a common manifestation of cirrhosis and does not necessitate immediate intervention. Peripheral edema and increased abdominal girth are associated with fluid retention in cirrhosis but are not as urgent as addressing altered mental status and confusion.
Sublingual nitroglycerin is administered to a male client with unstable angina who complains of crushing chest pain. Five minutes later the client becomes nauseated, and his blood pressure drops to 60/40. Which intervention should the nurse implement?
- A. Administer a second dose of nitroglycerin.
- B. Infuse a rapid IV normal saline bolus.
- C. Begin external chest compressions.
- D. Give a PRN antiemetic medication.
Correct Answer: B
Rationale: In this scenario, the client's symptoms of nausea and a significant drop in blood pressure suggest a potential right ventricular infarction. The appropriate intervention for this situation is to infuse a rapid IV normal saline bolus. This fluid resuscitation helps improve cardiac output by increasing preload, which can be beneficial in right ventricular infarction. Administering a second dose of nitroglycerin may further lower blood pressure. External chest compressions are not indicated in this case as the client has a pulse. Providing an antiemetic medication does not address the underlying issue of hypotension and potential right ventricular involvement.
The nurse is caring for a client with a chest tube following a pneumothorax. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Subcutaneous emphysema
- C. Crepitus around the insertion site
- D. Drainage of 50 ml per hour
Correct Answer: B
Rationale: Subcutaneous emphysema is the correct answer as it is most concerning in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, requiring immediate intervention to prevent complications. Oxygen saturation of 94% is acceptable and does not require immediate intervention. Crepitus around the insertion site may be a normal finding after chest tube placement and does not necessarily indicate a complication. Drainage of 50 ml per hour is within the expected range for a chest tube and does not require immediate intervention.
The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which assessment finding is most concerning?
- A. Crepitus around the tracheostomy site
- B. Dry and cracked tracheostomy site
- C. Yellowing of the skin around the tracheostomy site
- D. Mucous plugging of the tracheostomy tube
Correct Answer: D
Rationale: Mucous plugging of the tracheostomy tube is the most concerning finding in a client with a tracheostomy and thick secretions. This can lead to airway obstruction, which requires immediate intervention to maintain a patent airway. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but does not pose an immediate threat to the airway. A dry and cracked tracheostomy site may require interventions to promote healing but is not as urgent as mucous plugging. Yellowing of the skin around the tracheostomy site could indicate infection or impaired circulation, which should be addressed but does not pose the same immediate risk as airway obstruction.
